RSA encryption and decryption class written in Swift 2
This is the wrapper for Security framework written in Swift 2. It can do three things:
- It can generate public/private RSA keys
- It can encrypt NSData with public key
- It can decrypt NSData with private key
let text = "Hello World"
print("text to encrypt => \(text)")
let cryptor = RSACryptor(keySize: 1024)
guard let
data = text.dataUsingEncoding(NSUTF8StringEncoding),
rsaKeys = cryptor.generateKeyPair(),
encryptedData = cryptor.encryptData(data, key: rsaKeys.publicKey),
decryptedData = cryptor.decryptData(encryptedData, key: rsaKeys.privateKey),
decryptedText = String(data: decryptedData, encoding: NSUTF8StringEncoding)
else {
print("error")
return true
}
print("data to encrypt => \(data)")
print("encrypted data => \(encryptedData)")
print("decrypted text => \(decryptedText)")
Note : The keySize parameter is important. If you choose 1024 as keySize then you can encrypt max 1024 bit data.
That means data.length <= 128. Otherwise the encryption will be failed.
There is no licence. You can use it anyway you want.
